Fully developed laminar natural convection in a vertical parallel-plate duct with constant wall heat flux

Creator:: Aktan, Gülçin
Abstract:: The problem of heat transfer due to free convection in a channel formed by two parallel, isoflux, vertical plates is of considerable importance in electronic cooling applications, thermosiphons, the optimum spacing of plates or components, industrial stacks, heat exchangers, nuclear power plants and combustion involving vertical walls. Although in each...

Effect of initial conditions on the convergence rate of the energy equation in Couette flow

Creator:: Seddigh, Foad
Abstract:: Computers are very efficient in handling the problems which deal with iteration. Numerical treatment of the unsteady energy equation is one sort of iteration. The convergence of the unsteady film coefficient, in two dimensional space, to its steady state value has been deduced by comparison of the results of the...

A study of compression loading of composite laminates

Creator:: Berbinau, Pierre J.
Abstract:: The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

Creator:: Casey, Sean (Sean Michael)
Abstract:: Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

Elastodynamic analysis of a propagating finite crack in a micropolar elastic solid

Creator:: Han, Seog-young
Abstract:: A dynamic propagation of a finite crack of opening mode in a micropolar elastic solid was investigated. By using an integral transform method, a pair of twodimensional singular integral equations governing stress and couple stress was formulated in terms of the displacement transverse to the crack, macro- and microrotations, and...

Assessing Mass Diffusion Modeling in Premixed Flames

Creator:: Fillo, Aaron J.
Abstract:: Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

Modeling and control of a biologically inspired compliant structure

Creator:: Ray, Cody W.
Abstract:: We hypothesize that the extraordinary maneuverability and efficiency of bats in flight are in part due to the compliant nature of their wing structures. We utilize the parameters of bat bones measured by biologists to create a biologically inspired model of a flapping system consisting of a rotating hub actuator...
